C THE APPEAL
12 XL raises five grounds of appeal, which it accepts can be summarised into three closely related contentions of error:
(1) the insured risk is damage to property arising out of the use of a Vehicle required to be registered or have compulsory insurance and the writeback does not apply to the prime mover and trailer in the circumstances giving rise to the Claim (Grounds 1, 2 and 3) (Use Contention);
(2) the definition of Tool of Trade contains a second and third negative requirement, namely that the Vehicle which is the Tool of Trade must not be travelling to or from a Worksite and that it must not be a Vehicle that is used to carry goods to or from any premises (Grounds 1, 2 and 4) (Tool of Trade Contention); and
(3) the definition of Worksite could not properly be understood to include the road where the incident took place (Grounds 1, 2 and 5) (Worksite Contention).
13 During oral argument, XL sought to raise a fourth contention by reviving an argument which it made before the primary judge to the effect that Kerembla's own premises at Muswellbrook did not fall within the definition of Worksite.
14 The primary judge rejected Kerembla's submission on this point (at J [12]). His Honour concluded that there was no basis in the language used in the definition of Worksite to confine the concept in the way in which XL sought to do. Although XL did not challenge this finding in its notice of appeal, Kerembla was able to meet the argument, and the appeal proceeded on the basis of a challenge to the finding that Kerembla's Muswellbrook premises fell within the definition of Worksite. We will refer to this additional challenge as the Kerembla Premises Contention.
15 This appeal is not a dispute about principle, but rather the application of principle. There is no need to canvass the proper approach to construction of contracts such as the Policy. We need only refer to the well-known cases as to construction: see Darlington Futures Ltd v Delco Australia Pty Ltd (1986) 161 CLR 500 (at 510 per Mason, Wilson, Brennan, Deane and Dawson JJ); Johnson v American Home Assurance Company (1998) 192 CLR 266 (at 272-276 [19] per Kirby J, albeit in dissent); McCann v Switzerland Insurance Australia Ltd [2000] HCA 65; (2000) 203 CLR 579 (at 589 [22] per Gaudron J); Wilkie v Gordian Runoff Ltd [2005] HCA 17; (2005) 221 CLR 522 (at 528-529 [15]-[16] per Gleeson CJ, McHugh, Gummow and Kirby JJ); Selected Seeds Pty Ltd v QBEMM Pty Ltd [2010] HCA 37; (2010) 242 CLR 336 (at 344 [29] per French CJ, Hayne, Crennan, Kiefel and Bell JJ); Mount Bruce Mining Pty Ltd v Wright Prospecting Pty Ltd [2015] HCA 37; (2015) 256 CLR 104 (at 116-117 [46]-[52] per French CJ, Nettle and Gordon JJ); and Electricity Generation Corporation v Woodside Energy Ltd [2014] HCA 7; (2014) 251 CLR 640 (at 656-657 [35] per French CJ, Hayne, Crennan and Kiefel JJ).
16 Specifically, it is not in dispute that where there are two available readings of an insurance policy, preference should be given to a reading that limits rather than expands an exclusion clause: Dalby Bio-Refinery Ltd v Allianz Australia Insurance Limited [2019] FCAFC 85 (at [32] per Allsop CJ, Beach and Anastassiou JJ); see also Darlington Futures v Delco (at 510 per Mason, Wilson, Brennan, Deane and Dawson JJ).
17 It is convenient to proceed directly to the substance of XL's arguments by reference to the four contentions outlined above.
